    Opis:
    The aim of this work is to compare the environmental impacts of two production processes of tissue paper using virgin pulp (virgin fiber) or waste paper pulp (recycled fiber). This comparison is based on the materials and energy used as well as emissions and waste resulting from the production of tissue paper. Life cycle assessment (LCA), ReCiPe method, was chosen as the analysis tool. The results of the research proved that electricity has the most considerable participation in the overall environmental impacts in both production processes, followed by either virgin pulp or heat. Consequently, these two production processes are the greatest contributors to the following midpoint environmental impact categories: human toxicity, climate change, human health and ecosystems, and fossil depletion. The analysis based on endpoint impact categories proved that the production process based on waste paper is more environmentally friendly than the one based on virgin pulp in all impact categories: human health, ecosystems, resources. This is largely because of its lower material and energy requirements in the entire life cycle. Due to the fact that the tissue paper is the final use of fiber, using recycled waste paper is strongly recommended. The obtained research results are a valuable source of management information for the decision makers at both company and national levels required to improve the environmental performance of tissue paper production.

    Opis:
    This study presents a customized root cause analysis approach to investigate the reasons, provide improvements measures for the cost overruns, and schedule slippage in papermachine-building projects. The proposed approach is an analytical-survey approach that uses both actual technical data and experts’ opinions. Various analysis tools are embedded in the approach including: data collection and clustering, interviews with experts, 5-Whys, Pareto charts, cause and effect diagram, and critical ratio control charts. The approach was implemented on seven projects obtained from a leading international paper machine supplier. As a result, it was found that the main causes behind cost and schedule deviations are products’ related; including technical accidents in the Press section, damaged parts, design issues, optimization of the machine and missing parts. Based on the results, prevention measures were perceived.

    Opis:
    The effects of different volumetric ratios of bulking agents to pulp/paper-mill sludge on composting were studied. Rice husk and corncob were used as bulking agents. Volumetric ratios of bulking agents to pulp/paper-mill sludge were used as 10:100 and 25:100. To monitor the evolution of the composting systems, routine parameters such as temperature, moisture, pH, total N, NH4 +-N, NO3-N, total C, and C/N ratio were analyzed. The results indicated that the agro-based materials significantly affected compost maturity parameters. Moreover, the quality of the product obtained in the composting process treated with the agro-based materials achieved satisfactory stabilization and sanitation for application to land.

    Opis:
    The article presents a new technique for measuring paper deformation in unidirectional tensile tests, based on recording and analysis of a series of specimen images. The proposed technique differs from the DIC-based deformation measurement in that the cross-correlation of image data has been replaced with linear filtering. For this purpose, a regular grid of markers is printed on the sample. Filtering the image creates local maxima in the places where markers occur. The developed algorithm finds their location with sub-pixel accuracy. Printing a grid of markers on tested paper and use of reference objects visible in the same image as the paper sample, freed from the need to mechanically connect the camera and the universal testing machine and from the necessity to electronically synchronize their work. The obtained deformation distributions and Poisson’s ratios are in accordance with the literature data which confirms the correctness of the developed measurement technique.

    Opis:
    The profile of microbial diversity in a NABR digesting RPMW was investigated using phylogenetic analysis of partial 16S rRNA sequences by a neighbor-joining-tree, supported by microbial morphology analysis by SEM. The results showed that microorganism inside NABR consisted of dominant Bacillus (25 strains) and Bacterium (1 strain) which were isolated from the settled sludge at the bottom of the reactor, whilst Bacillus (2 strains), Pseudomonas (2 strain) and Chryseobacterium (2 strain) were isolated from the biofilm formed on the packing material. It revealed that the microbial community strains, function, and structure changed simultaneously throughout the reactor system. The microscopic results showed rich biofacies, while the dominant microorganisms have various morphologies in every compartment of the system. It consisted of a long rod-shaped and filamentous bacterium composed majorly of bacilli of different sizes. Although the study successfully analyzed the microbial diversity and morphology in the system, the microbial communities reported in this study were different from other similar studies. This may be caused by the application of a culture-based technique that usually provides limited information due to the number of barely cultivated or uncultured strains.

    Opis:
    The aim of this study is to examine the importance of the decision in Engelhart CTP (US) LLC v Lloyd’s Syndicate 1221 with regard to the insurance of economic losses and non-existent goods in the context of all-risks cover. It also strives to analyse to what extent the principles of construction described in this decision are applicable to the interpretation of all risks cover in marine insurance disputes subject to Polish law. Assureds and beneficiaries of cargo policies are defrauded into taking up false documents for non-existent goods yet Polish law fails to address the questions which arise in such situations. It is thus important not only to investigate and evaluate the answers provided by English law but also to explore if and how Polish law may employ them. It follows from this study that Engelhart may be used in construction of all-risks policies subject to Polish law in most scenarios.
    Celem niniejszego opracowania jest zbadanie znaczenia wyroku w sprawie Engelhart CTP (US) LLC v Lloyd’s Syndicate 1221 w odniesieniu do ubezpieczenia szkód ekonomicznych i ładunków nieistniejących w kontekście polis „all risks”. Próbuje ono także przeanalizować w jakim zakresie zasady wykładni przedstawione w tym wyroku można zastosować w interpretacji polis „all risks” w sporach ubezpieczeniowych opartych o prawo polskie. Ubezpieczający i ubezpieczeni w zakresie polis ładunkowych w wyniku oszustw przyjmują fałszywe dokumenty na nieistniejące towary, jednak prawo polskie nie odnosi się do wątpliwości, które wówczas powstają. Jest zatem istotne nie tylko, aby zbadać i ocenić rozwiązania oferowane w tym zakresie przez prawo angielskie, ale także aby wyjaśnić czy i jak prawo polskie może je wykorzystać. Niniejsze opracowanie wskazuje, że wyrok w sprawie Engelhart może w większości przypadków zostać zastosowany przy wykładni polis „all risks” poddanych prawu polskiemu.
